Especially in continuous coating lines such as color coating lines, tin chrome plating lines, the wavy strip is leveled by giving controlled elongation up to the plastic deformation limit. The system is designed as fully automated and the strip is leveled according to the wave condition and properties. In this way, the coating quality is increased and the products are produced in A1 quality. We have developed tension leveler system so that we ensure that the strip is of high quality and smoothness for coating by giving elongation at certain values in a sensitive and controlled manner and by giving proportional pressure to the rollers.
